Schneider Digitar wide-angle lenses meet high quality requirements concerning contrast and resolution, correction of distortion and absence of color fringes. At the same time, with an image circle of 60 to 110 mm they have capacity for adjustment, correction of perspective, “converging lines” as well as for depth of field control according to the Scheimpflug law as is to be expected of professional large format photography.

Lenses designed for infinity lose sharpness and dis­tort when applied to higher magnifications approaching 1:4 (or higher). The Apo-Digitar M lenses have been optimized for a 1:1 reproduction ration, with excellent performance in the 1:4 to 4:1 range. This allows image quality at or beyond the limit of the performance of current high-resolution chip backs.
